The ends 6 are .be noted, still lessfriction is produced by 55 corrugated and contact, wit-lithe peripheriesreason of the small amount of bearing surof the balls 7 which aredisposed between the face between the rollers, shaft, and casing.

Tn Fig. a still further modification is illustrated in which the rollers22 hear at either end upon the recessed collar 29', can

ried by the shaft, and the similarly recessed wail of the casin Thereduced ends 23 are eircumterentially recessed to provide a bearingsurface for one of the flanges of the rings 2%. The other flange of therings is formed with an arc-shaped recess to provide a raceway for theanti-friction balls.

In Fig. (i a still further modification is illustrated in which therollers 30 contact with the peripherally concaved collar 30 at eitherend thereof. The channel rings 31 are supported upon the convex ends ofthese rollers which are separated from each other by the balls 32 whichrotate in the raeeways formed by the outer curved flanges of the rings.

It will be noted that, in each of the forms shown the channel rings areemployed, which is the principal feature of my invention, as itmaterially adds to the ease of operation of the same without the leastadditional friction. This result has long been desired inbearings ofthis class, and I haveatt-ained it in any one of the forms shown anddescribed in the foregoing specification. My invention is moreoversimple in construction, compact l v arranged and readily put together.it will also be found highly eilicient in operation, durable in use andextremely inexpensive to manufacture.

My improved be 'aring may be advantageously used in -onnection with awheel shaft, or upon power shafts revolubly mounted in journals. as usedin the eonstruc= tion and oieration of various machiner Havin thusdescribed my said inven ion, what; I c him as new and desire to secureby United States Letters Patent is:

l. A bearing of the class described comprising'a' easingfl havingremovable ends, a

peripheral shoul or disposed centrally within said casing, a shaftextending therethrough, rollers in frictional engagement with said shaftand said shoulder having reduced ends, and channeled rings comprisingtwo hin' ed sections provided with a pluralityot openings and supportedupon the reduced ends of said rollers, the inner flange of said ringsbeing split.

2. A bearing of the. class described. comprising a casing, havingremovable ends, a peripheral shoulder disposed centrally within saidcasing, a shaft extending there through, rollers infrictionall'engagcinent with said shaft and said shoulder havii'igreduced ends, outwardly flared peripheral plates secured on said shaftfor preventing the longitudinalmovement of-said rollers, and channeledrings comprising two hinged sections each provided with a plurality ofopenings and supported upon the reduced ends of said rollers, theinner-flange of said rings beings'plit.
